fore administration of the glycoside a solution of 3-(2,2,2-
trimethylhydrazinium) propionate was propholactically ad-
ministered intravenously, the ECG was recorded in II standard
lead.
It was found that in the dose of 10 mg/kg the pre-
paration increased the arrhythmogenic dose of Strophanthin
G from 67+9 to 90-15 ug/kg (Table 4). At a further in-
crease of the dose of the preparation to the present inven-
tion its protective effect was increased too.

~ herefore, the pharmaceutical preparation based on
3-(2,2,2-trimeth~lh~dr~zinium)propionate in patients
with verified ischemic disease provides the inotropic
effect on the myocardium, remo~es retrosternal pains
and rhythm disorders ~uch as extrasystole.
Consequently, the ph~rmaceutical preparation
according to the present invention fea-tures a special scope
of activit~; it m~nifests itself a~ a ~asodilative prepa-
ration relative to coronary arteries, facilitates imprQVe~
ment of the myocardial metabolism and posse6ses a clearly
pronounced and stable positi~e inotropic ef~ect.
~ he pharmaceutical preparation ac~ording to the pre-
sent invention is preferabl~ administered in the form of
injectio~ solutions, tablets~ capsules, powders. It is in-
dicated at the rate of 10 to ~0 m~kg of the bodyweight
as tablets or cap~ules per da~ simultaneously with taking
meals, or i~ the form of 10-40% injection solution~ ~he
preparaticn of the present invention relates to low-toxic
~ubsta~ces ~ist B or even les~ strict).
Pharmaceutical forms o~ thc preparation for peroral
administration are stable for two years at room temperatu-
re and are to be stored in a dry~ ht-protected place
Injection solutions should be stored for ~ot more than 2
years at a temperature of not more than +5C.
